Pulmonary fibrosis is currently a difficult disease worldwide, and therefore the treatment of this disease is relatively difficult for both TCM and Western medicine objectively speaking. However, Chinese medicine has its own unique theoretical system, and the treatment of diseases is based on the four diagnostic examinations to collect information and discriminate treatment, so it has unique advantages in the treatment of many difficult diseases. Compared with the application of hormones and other immunosuppressants in the treatment of pulmonary fibrosis in Western medicine, Chinese medicine has the characteristics of less side effects and various methods. However, it should be noted that TCM treatment is more individualized and the prescription is different for each person. In addition, the treatment of pulmonary fibrosis is a long-term process and it is impossible to hope for a short time to solve the problem. Therefore, patients should be prepared for long-term treatment.
